I looked at one of the popups that I have not installed yet. And yes, with just a little bit of force, you can rotate the piston clock-wise. With that little tidbit of information, this forum just saved me hours of frustration for when I get the next set of pop-ups installed.

I dont think you understand the racheting explanation. While your system is on just grab the entire piston and rotate left or right. as it rotates youll hear clicking. This is Ok. When we say piston we are talking about the black rod that pops up and the nozzle screws on to. Rotate the entire piston.

In your area, United Pipe & Supply, Irrigation Specialists, and Ewing Irrigation all carry them. As far as online, I am not sure who distributes MPR online.

Where do you buy these nozzles, I haven't seen them online?

I didn't realize the little white thingy in the bottom of the pop-up works like a ratchet. I'll have to look into that more. I've been shutting off the water, openning the pop-up, and popping off the white thingy to reposition it.

Thanks for the input. I'll see what I can make of it tonight.

Both Rainbird and Toro popup mist head bodies have a ratcheting adjustment, so you just grasp the piston that is popped up, and rotate it as needed, while the zone is running.

it is correct, at any places in the garden you can not life without the other Spray-nozzles.Think it is not rational to mix the Spray-nozzles with the MP-or Rotary-nozzles. the amount of water is very diffrent.
Let us hope that the engineers make more from this fantastic idea...

And since we're on the subject that I've installed some of these, here's my feedback so far...

I love how easy it is to set where the end of the arc is while they are running. But having to shut down the system, open the spray head, and attempt to gingerly adjust that positioning ring in the spray head is a pain. Obviously the Rainbird design of the spray head is partally to blame, but it would be nice if there were a simple way to adjust the MP Rotators Left Side start position while the system is running.

I've also found the MP Rotators difficult to adjust for distance. First of all, the screw is so small that using a screw driver is very difficult. It takes a lot of force, relative to the size of these little screw drivers, so it's easy for the screw driver to slide off the screw. Additionally, it seemd that some of the MP Rotators just would not adjust no matter what I did with that screw. But if I swapped out the Rotator for another one (same size/type), I could properly adjust it.

So the bottom line feedback I have on the MP Rotators is that I like their performance, tuning them is a painfully arjuous task if you're working by your self. (Of course the same might be said of the nozzles, I'm just not sure. This is my first irrigation project, and the research I did seemed to say "use MP Rotators rather than Nozzles).

I'm not comparing MP Rotators to Rainbird rotors. I'm comparing MP Rotators to Rainbird spray nozzles that the MP Rotators replace (i.e. they fit into the 1800 spray heads inplace of the nozzles).

As for something under 90 degrees, there's plenty of places where people have sidewalks that are at an angle other than 90 degrees to their house, driveway, etc. So there are lots of situations where you'd want to place a spray head in a corner, but that corner is tighter than 90 degrees. For these situations, there are adjustable nozzles that can adjust down to pretty much 0 degrees. So in those places where you'd otherwise use a nozzle set at perhaps 45 degrees, if you replace that nozzle with a MP Rotator, you will be watering more than your 45 degrees desired.

I've also got a situation where the landscaping is in odd narrow shape. One possible arraingment would place a sprayhead at the edge of this landscaping and require a spray angle of about 300 degrees if I only want the lawn watered. Again, Rainbird adjustable nozzles would allow me that 300 degrees. But the MP Rotors make me choose between 270 degrees, 360 degrees, or adjust the position and/or count of spray heads. (Because I've liked the idea of the MPRotators so much, I've just opted for 360 and water the landscaping with the lawn.)

BTW, I've now got a small set of these MP Rotators installed, so I've now seem them in action. Even at less than 90 degrees, they would still be rational. It's just that if the angle is small enough that you might not have both a "long" beam and a "short" beam at the same time.

...do you read from the same Nozzles????
If you buy the Rainbird rotary for one Dollar, I take 1000 of them...`
The MP Rotator`s spray-angle is 90-210 degree- that is correct,but
the Rainbirds is 90 OR!!! 180 - and over!
I Have never seen a garden with only 90 degree angles...( sorry Rainbird`s)

If you see this Nozzle in action - you understand that under 90 degree is not rational, it makes then only 3-4 ( beams? )
(look to the pic. No. 17 from the gallery of my home-page) and you understand...

and remember- this Nozzle-system is very young, 1-2 years later... we will see...

The MP is my faforite-
absolutely -letsrain
